A federal indictment says the conspiracy involved 500 grams or more of a mixture with a detectable amount of meth. Louisville police previously said there were "large amounts of narcotics" within the vehicle at the time of the traffic stop that turned deadly.

Detectives pulled over a white pickup truck in February with four passengers and were met with gunfire from the vehicle, which struck one detective in the head. The other officer returned fire, ultimately killing two occupants.

The two surviving passengers, Goodman and Mark Alan Risner, 41, were arrested and charged with first-degree trafficking in a controlled substance. Both have since been indicted by a grand jury and are scheduled for a preliminary hearing next month and a jury trial in December.

Goodman was also charged in state court earlier this month in a separate case, after detectives executed a search warrant and found suspected drugs. He's due next in court on those charges on April 24.

A news release on Goodman's federal indictment notes that he is currently in state custody but will be remanded to federal custody for an initial appearance. The court date has not yet been scheduled.

If convicted at federal trial, Goodman could be sentenced to at minimum 10 years in federal prison, as well as being fined and put on probation, according to the release from the U.S. Attorney's Office.
